Answer:

4x + 5 = 29

Step-by-step explanation:

x = # of coins in pocket, and you have 4 times that much. Add five to that, and you have a total of 29.

Answer:

4x+5=29

Step-by-step explanation:

let x=the # of coins in my pocket

4 times the number of coins in my pocket plus 5 more is 29 =

4x+5=29

Therefore, there are 3 boys for every 4 girls.

Answer:

38.42cm

Step-by-step explanation:

Given that the length of the sides of a rectangle are 30 cm and 24 cm.

The length of the diagonal can be obtiaed using Pythagoras rule

Length of the diagonal = hypotenus

Hypotenus = sqrt(opposite ² + adjacent ²)

Opposite and adjacent sides are 30cm and 24 cm

Hypotenus = sqrt(30² + 24²)

Hypotenus = sqrt(900 + 576)

Hypotenus = sqrt(1476)

Hypotenus = 38.419

Length of diagonal = 38.42cm

Answer:

$5820.07

Step-by-step explanation:

Substitute 243 into the equation for n:

[tex]c=117\sqrt[3]{243^{2} }+1264\\c=117\sqrt[3]{59049}+1264\\c=117*38.9407384+1264\\c=4556.06639+1264\\c=5820.06639[/tex]

Round 5820.06639 to the nearest hundredth:

5820.07

$5820.07

Answer:

volume of Sphere B is 8 times greater than the volume of Sphere A

Step-by-step explanation:

Sphere A:  V = 4π (2^3)/3 = 32π/3

Sphere B:  V = 4π (4^3)/3 = 4π(64)/3 = 256π/3

volume of Sphere B / volume of Sphere A =  (256π/3)/(32π/3) = 8

Answer:

68/99

Step-by-step explanation:

Answer:

40 kilometers

Step-by-step explanation:

the hypotenuse is a² + b² = c²

so first we have to get 32 and 24 into ²

            32² = 1024       (32 × 32)

            24² = 576         (24 × 24)

1024 + 576 = 1600

now we need to find the square root of 1600

√1600 = 40     (calculator)

therefore, the hypotenuse is 40 kilometers

goodluck, hope this helped,

Answer:

c=17

Step-by-step explanation:

Pythagorean theorem helps you find out the length of a missing leg or hypotenuse of a right triangle.

c=[tex]\sqrt{a^2+b^2}[/tex]

c=[tex]\sqrt{8^2+15^2}[/tex]

c=17

Answer:

Step-by-step explanation:

Answer: height is 2

Step-by-step explanation:

A = 1/2bh

A = 3; b (base) = 3. Substitute these values in the formula and solve.

3 = 1/2*3*h = 3/2 h

h = 3 * (2/3) = 2

Answer:

Height = 2

Step-by-Step Explanation:

So, I'm not sure if "gh" is a measurement. But I'm thinking it should be solved like this.

Area =  3gh

Base = 3gh

Height = ?

Plug & Chug

3gh = 1/2 (3gh)(h)

2/1 · 3gh = 1/2 (3gh)(h) · 2/1

[tex]\frac{(2)(3gh)}{(3gh)\\}[/tex] = [tex]\frac{(3gh)(h)}{(3gh)}[/tex]

h = [tex]\frac{(2)(3gh)}{(3gh)}[/tex]

h = 2
